MACHINE FOR MANUFACTURING CAPSULES FOR BOTTLES OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 664,516, dated December 25, 1900;

Application filed June 25, 1900. Serial No. 21,571. (No model.)

To all whom, it may concerni Be it known thatI, EDUARD WATZKE, asubject of the Emperor of Austria-Hungary, residing at Friedberg, in the Province of Styria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Machines for the Manufacture of Capsules for Bottles or the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to figures of reference marked thereon, which form a part of this specification.

The object of this invention is to construct a machine for making capsules for bottles and i the like from tin-foil, which machine automatically and successively performs the transformations of the blank heretofore effected by three different machinesnamely, the cutting out of acircular disk from an endless tin foil strip, the drawing of this disk into the form of a cup or dish, and the stretching or extending of this cup or dish into the form of the finished capsule-and therefore only requires the insertion of the strip to be worked from time to time, but does not require to be specially watched. I This machine comprises, essentially, a cutting press or punch to which the tin-foil strip is fed by two intermittently-actuated feedrollers, a drawing press or punch of known construction into which the disk cut by the first press or punch falls, an adjustable feedhopper which receives the blank falling down out of the drawing-press, and a stretching device in which the dished blank is introduced by the feeding device in order that it may be show the cut-out disk, the dished blank, and the finished capsule.

Fig. 8 is a vertical section through the c.utting-press,with the punch depressed. Figs. 9, 10, and 11 show the drawing-press with the punch in three difierent positions. Figs. 12 and 13 show the stretch-' ing device in two positions, corresponding to the beginning and the end of the stretching.

On the base-plate 1 there rests on feet 2 a rectangular frame 3, which is provided with a bearing arm or bracket 4 for the main shaft 6, having at one end a belt-pulley 5, provided with means for throwing it into and out of gear. The main shaft 6 is supported at its other end in a bearing 7 and drives, by means of the bevel-wheels 8, the transverse shaft 9 for the drawing-press, mounted in the frame 3.

Beneath the shaft 6 the two short shafts l3 and 14. are mounted in bearings 10 11 and in the frame 7 and bearing 12, respectively, Fig.

3. These short shafts are driven from the main shaft 6 by means of the gear-wheels 15 16, respectively; The shaft 14 drives, by means of the bevel-wheels 17, the transverse shaft 18, which runs in bearings 19 20, mounted on the base-plate 1.-

The tin-foil or sheet-tin to be worked is placed in the form'of a roll 21 in hearings or recesses in arms 22, secured to the frame 3, and the strip of tin-foil 23 as it is drawn 0% is fed through a guide-channel 2 1 to the feedrollers 25 25, which are mounted in two forked brackets 26, secured to the frame 3, and are connected together by interengaging gear-wheels 27. The driving of the feedrollers is'efiected by means of a ratchet-wheel 28, mounted on the axis of the lower roller 25, in which ratchet-wheel there engages a pawl 30, mounted on the oscillating lever 29. The said lever 29 is connected by a link 31 with the adjustable pin 32 of the crank-disk 33, which is mounted on a short shaft 35, supported in the frames 34 and bearing a chain-wheel 36, which is driven by a chain 37 from a chain-wheel 38 of equal size, mounted 011 the shaft 6. complete revolution of the shaft 6 the tinfoil strip 23 is fed forward through a definite distance by the rollers 25 (this distance being capable of alteration by adjusting the crankpin 32 in the groove of the disk 33) and is then held fast by the said rollers, which re- Oonsequently at each.

main stationary after each forward motion. The tin-foil strip passes through the guidechannel 39 over the die or matrix 40 of the cutting-press, which is detachably secured to the perforated horizontal plate 41 of the frame 34. The punch 42 of the cutting-press is inserted into the lower end of a slide-block 44, movable in a vertical guide 43, mounted on the frame 34, and is surrounded by a stripping or ejectingring 45,which is continually pressed downward by a spring 46. The punch is actuated by an eccentric-pin 47, mounted on the shaft 35, which pin engages in-a horizontal groove in the slide-block 44, Fig. 1. While the feed-rollers are at rest, the punch 42 moves down and cuts a circular disk 48 out 'of the tin -foil strip 23, Figs. 5 and 8. This disk 48 falls into a guide-channel 49 and from thence passes into a pocket 51, arranged in front of the die or matrix 50 of the drawing-press. In the upward motion of the cutting-punch 42 the ring 45, under the action of the spring 46, strips the perforated tin-foil strip from the punch 42.

The die or matrix50 is detachably mounted in a common or well-known manner in front of an aperture in the frame 3, in which the die 52, which may be provided, if desired, with letters or other characters or devices, can

be adjusted at will by means of the screw 53. 1

. The punch 54 of the drawing-press is provided at its end with a let-in piece of lead andis secured in a plunger 55, which is guided horizontally in the cross-piece56 and is driven from the shaft 9 by meansof the crank 57 and has pressed the disk 48 against the con During. this operation the punch 54, which is driven and connectingrod 58. The punch 54 is concentrically surrounded by the sleeve 59, which is secured to a cross-piece 60, connected to rods 62, which are arranged on both sides of the plunger 55, are guided in the cross-piece 56, and are connected together by a transverse bar 61.

On the shaft 9 thereare mounted opposite the end of the rod 62 cams 63, which serve for moving the sleeve 59 relatively to the die 50. The return motion of the sleeve 59 is efiecte'd by springs 64, which surround the.

rods 62 and bear against the cross-piece 56, Fig. 2.

In the position of the parts shown in Fig. 1 there is a disk 48 in the pocket 51. shaft 9 continues to turn in the direction in.- dicated by the arrow, the punch 54 and the sleeve 59 are simultaneously moved relatively to the guide 50. By reason of the form of the cams 63 the sleeve 59 remains stationary after it has reached the position shown in Fig. 10

ical part of the recess in the die 50.

by the crank 57, moves farther forward, brings the disk into the form of a cup or dish 65, Fig.

11, and imparts the desired impression to the During, this operation the bottom thereof. steps of the cam 63 pass the ends of the rods 62, and the cross-piece 60, together with the sleeve 59, is moved back rapidly by the springs 64 into the position shown in Fig. 11. r The punch 54 moves back, whereupon the now If the stationary sleeve 59 pushes the blank 65 away from the punch. The blank falls into' an arrangement which feeds it to the stretching device arranged beneath the drawing-press. This feeding device consists of a forked piece 66, Fig. 4, which is secured to a horizontal rod 67 and is provided with a funnel-shaped extension 68,which conductsthe falling blank into the fork 66, Fig. 3, in which it remains. The rod 67 is guided horizontallyin two arms 69 70 on the bearing-bracket 11 and is driven by a stepped cam 71, mounted on the shaft 13. Aspring 72 presses the rod 67 by means of the roller 73 continually against the periphery of the cam 71.

The stretching device consists of a horizontal spindle 76, running in bearings 74 75. It bears a fast pulley 77 and aloose pulley 78 and is driven at a high speed by means of a belt. On the right-hand end 79 of the spindle 76, Fig. 1, which is made somewhat conical, corresponding to the form of the finished capsule, is mounted a sleeve v80, which by means of a screw 82, engaging in a longitudinal slot 81 in the spindle 76, is guided on the latter.

This sleeve is reduced at its righthand end in such a manner that it fits into the recess in the blank 65 and is continually pushed toward the right by means of aspring 91. As an extension of the spindle 76 there is arranged a horizontal sliding rod 84, guided in a bracket 83, the rod 84 being prevented from rotating by a screw 86, engaging in a groove 85 therein, and being pressed constantly by a spring 87 against the periphery of the stepped cam 88, which actuates it, and is mounted on the shaft 18.

On the lefthand end of the rod 84 is pivotally mounted a punch 89, which bears an indiaerubber ring 90.

92 is the pressure or spinning roller, which can be introduced, with its holder, into a slide -block 93, which is capable of being moved perpendicularly to the spindle 76. The said slide-block is guided in a slide 97 and is provided with a transverse groove 94,

tal rod 104, Fig. 3, which is curved in order to avoid the bearing 75 and is pivotally connected to the lever 96 at its front end. This rod is actuated by means of a cam 10 mounted on the shaft 13. A spring 106 presses the .rod 104 by means of its roller 107 continually against the periphery of this cam. While the blank 65 is being stripped by means of the sleeve 59 from the punch 54.01 the drawing-press, the feed-hopper68 is in the position shown in Fig. 4, so that it receives the blank and conducts it into the fork 66. The rod 67 is now fed forward by the cam 71 and brings the fork 66, with the blank, into line with the stretching-spindle 76. The punch 89 moves, under the action of the cam 88, against the fork 66 and pushes the blank onto the con ical end 79 of the spindle and holds it fast thereon. Since the spindle rotates, the blank and the punches 89 90 must also rotate therewith. The fork 66 now springs back into its original position under the action of the springs72. Thepressureorspinningroller92, which during this time has been moved back with the slide 97 toward the right, is moved by the lever 96, with the slide-block 93, toward the spindle and comesinto the position shown in Fig. 12. From there the pressure or spinning roller, under the action of the disk-crank 98, moves along the spindle 76 and as it pushes back the sleeve 80 stretches the blank 65, which receives the form of the conical end 79 of the spindle 76. After the spinning-roller has reached its outermost position, Fig. 13, the lever 96 is rapidly oscillated by the spring 106 in such a manner that it removes the slidebiock 93, and with this the spinning-roller from the stretching-spindle. During this operation the sleeve 80, under the action of the spring 91, moves along the spindle and strips the finished capsule 108 from the spindle.

In order to prevent the stripped-off capsule, by reason of the rotation imparted to it by the spindle, from being shot out laterally, a lever 110 is pivotally mounted at 109 on the base-plate 1, which lever is provided at its front upper end with a small brake-shoe 111, of leather or other material. This lever is actuated toward the end of each stretching operation by a pin 112, mounted on the gearwheel 15 in such a manner that its front end 111 touches the capsule 108, and therefore prevents it from rotating rapidly at the moment of stripping.
